DESCRIPTION
The
SP503
is a highly integrated serial transceiver that allows software control of its interface
modes. It offers hardware interface modes for RS-232 (V.28), RS-422A (V.11), RS-449, RS-485,
V.35, and EIA-530. The
SP503
is fabricated using low鈥損ower BiCMOS process technology, and
incorporates a
